v AHEIFITEH REINHABD THOSS AND PAUL RGHRICH, OF ALTON-A, GERMANY.

mANeLE.

To all whom'it may concern:

Be it known that we, REINHARD THoss and PAUL RoHRIoH, both citizens of the German Empire, residing at Altona, Germany,

5 have invented new and useful'lmprovements in Mangles,- of which the following is a speclfication. j Y

Our invention relates to improvements in mangles in which one of the rollers can be Withdrawn from the other and the object of our invention is to provide a device in such mangles permitting the disengaging and enga ing of the roller-gearing when the said ro er. is withdrawn from or approaches the other roller.

We attain our object by the construction illustrated on the drawing herewith in which -Figure 1 is a front-view of a mangle, partly.

in section, provided with our improvements as herein described and set forth, Fig. 2 is an end view of the same, also partly in section, Fig. 3 shows the arrangement and movement ofthe radial adjusting lever herein below re-. ferred to, being a detail view of a portion of Fig. 2, and Fig. 4 shows how the several levers hereinafter mentioned are connected with each other, being a detail view of a porone on eac tion of :Fig. 1.

As shown in the said drawing there is mounted in the ordinary way in the frame a the upper, stationary calendering roller 7) provided at one end with a cog-wheel 0. Be-

neath the said roller is another roller d which is movable in vertical direction being supported by a Ipair of vertically sliding pieces 1', end, sliding in the frame (1. Above the cog-wheel c is the driving shaft e on which is mounted a pinion movable in axial direction and controlled y a lever h, theupper furcated end of the same engagin the hub of the said pinion which is extende and flanged. The said pinion with the upper end of the said lever and thecog-wheel a may and is connected with and slides in an outward inclined slot in arm Z. The said slotted arm is pivotally secured to the shorter arm of a radial adjusting lever k which is fulcrumed Specification of- Letters Patent. Application filed July 26, 1906. Serial means.

to the frame a at Ya. said radial lever has a gri while the other end is jointed to a link m t e bottom end of which is pivoted to an eccentric disk 0 at- The outer end of the i tached to the end of a shaft n parallel to and atlsome distance beneath the roller d. On the other end of the said shaft n is another eccentric disk or a cam 0, both disks being of the same form and both rigidly securedon the" shaft n, each of the two eccentric disks supporting a sliding piece p guided in the frame of the machine, the two pieces being adapted to act upon the afore-mentioned pieces r supporting the roller d. Between the said sliding pieces 1) and r there may be provided intermediate elastic members, for instance cylindric springs 8, one of which is shown in Fig. 1 in vertical section, or flat springs or the like. Lying upon the feeding board or table which is attached to the frame a as usual, is a piece of cloth i corresponding I smoothening.

' Our improved mangle works as follows: The cloth 6 secured as mentioned at one end to the upper roller 1) is spread upon the table of, the mangle and the linen or other articles intended for smoothenin placed and equally distributed on the said 0 0th; thereupon the lever is should be turned. downward and a rotatory movement imparted to the flywheel. The' downward movement of the lever is, that is of the outer arm of the same,

causes an upward movement of-the inner arm which draws the link 'm upwards and through the action of the aforesaid eccentrics o and the sliding members p and 1", lifts the roller d holding it tight against the upper roller 1) until released. At the same time the slotted arm Zis lifted, the lever it being forced thereby to move outward in the said slot and correspondingly the top-end of the said lever h moves inward, pushing along the pinion f which meshes in and engages the cog-wheel c causing thereby a rotatory movement of the rollers and operation of the mangle, the

aforesaid cloth i with the linen thereon being wound around the upper roller. On' releasing the lever is the several lparts assume again their former positions, t e pinion f disengaging from the cog-wheel c, the aforesaid sliding members and with them the roller (1 dropping by their wei ht and the movevment of the eccentrics, t e fall of the lower roller being cushioned by the aforesaid elastic members. On pulling back the cloth the smoothened linen may be removed and replaced by a new supply.

We are aware that mangles were in use heretofore with one roller capable of being vtiithdrl'lawn {1mm theother and so were mang esw eret e care a ing and disen a in permitted a sal e and c orl venient feedili g bui the characteristic of our invention is the combination of the two features, both working simultaneously by the mere operation of a lever and securing a grade of safety in the operation of the machine and economy in time which the old machines were unable to We claim: In a mangle in which a pair of rollers operrate, one of which is adapted to be withdrawn from the other bemg "ournaled in vertically slidingsupports guided in the frame of the said mangle, the combination '(Z)'provided with an outwardly inclined slot plvotally secured thereto, an axially movable lever (h,) the upper end of the same engaging the hub of the said pinion and the lower end moving in the said slot, eccentrics (0) supporting the sliding supports of the lower roller and a member (m) connecting the rear end of the said radial handled lever (is) with the corresponding eccentric, substantially as de scribed.

In testimonywhereof we have signed our names to this specification in the two subscribing witnesses.
